Anbox Cloud 1.9.0 has been released

Introduction

The Anbox Cloud team is pleased to announce the release of Anbox Cloud 1.9.0

Deprecations

  • The Android 7 (bionic:android7:arm64 and bionic:android7:amd64) images are now deprecated and will no longer be available starting with Anbox Cloud 1.10 which will be released in April 2021
  • The UI included in the Anbox Stream Gateway service will be dropped in Anbox Cloud 1.10 as it’s being replaced with the new dashboard

Known Issues

  • At times the anbox-cloud-dashboard charm reports a error as workload status due to too many units trying to use apt on the machine at the same time. Juju will retry the installation after some time automatically and the problem will fix itself. The issue can be identified in the output of juju debug-log --include anbox-cloud-dashboard. This will be improved in the upcoming 1.9.1 release
  • If for the initial deployment not Ubuntu Advantage token is configured via an overlay.yaml the status messages reported by the charms once they become idle is not set to UA token missing. There is no impact in terms of functionality. Applying the UA token via juju config <application> ua_token=<token> will work as usual.

New Features & Improvements

  • New web based dashboard to manage applications and streaming sessions in Anbox Cloud
  • Webview based on upstream 88.0.4324.152 release
  • Android security updates for February 2021 (see here for more details)
  • Out of band data allowing to send custom data from applications running inside the Android container to the client connected over WebRTC
  • Support for streaming the clients camera to the Android container over WebRTC
  • Hardware video encoding support for Nvidia on Arm
  • Support in AMS for existing LXD clusters
  • New recursive= parameter to GET /sessions on the Stream Gateway to return the full session objects rather than just their ID
  • Streaming sessions can now be deleted in batch and asynchronously
  • Introduce the container.features config item in AMS to enable specified features in Android container
  • Bump key size to 4096 to work with 20.04 stronger security defaults
  • Anbox now uses Vulkan as a backend renderer API on Nvidia GPUs on both x86 and Arm. This improves performance, stability and compatibility.
  • Improved density on Nvidia Tesla T4 cards. With Anbox Cloud < 1.9.0 the maximum of containers possible was around 10-12 due to bugs in the GPU firmware when using the OpenGL ES client API. With the switch to Vulkan the firmware bugs are no longer triggered and up to a maximum of 32 simultaneous containers are possible (subject to their actual use of the GPU)
  • Updated Nvidia GPU driver to the 460 series for both x86 and Arm
  • A default virtual keyboard is now included in the provided Android images and can be conditionally enabled
  • A launch activity can now be specified when new sessions are created or existing joined. This allows switching to specific activities within the application.
  • Stripped down unnecessary dependencies to speed up deployment time
  • Session objects in the gateway now contain information about failed container
  • The AMS charm now sets up access to the Anbox Cloud image server via the Ubuntu Advantage subscription the machine is attached to. It’s no longer necessary to supply individual user+password authentication details
  • Added API measurements to metrics
  • Various fields of an application can now be updated via the AMS HTTP API without providing a new APK file
  • The Anbox Stream Gateway has now support for HTTP rate limit which can be configured via a charm configuration option
  • AMS can be configured to use pre-existing storage pools and networks
  • AMS now exposes the scheduler.strategy configuration item to allow choosing between binpack and spread strategies
  • AMS now exposes two configuration items node.queue_size and node.workers_per_queue to allow fine tuning how AMS processes container launch requests for optimal throughput
  • The Google STUN server is no longer used
  • Streaming sessions are now ephemeral by default and will be automatically removed when the container it belongs to terminates
